Description and Introduction

3.3-V Low-Voltage Quadruple FET Bus Switch with 5-V Tolerant Level Shifter The SN74CB3T3125PWR is a high-bandwidth FET bus switch manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 2.3V to 3.6V  
- **On-State Resistance (RON):** 5Ω (typical) at 3.3V VCC  
- **Bandwidth:** 200MHz  
- **Input/Output Capacitance (CI/O):** 10pF (typical)  
- **Propagation Delay:** 0.25ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-14 (PWR)  

### **Descriptions:**  
- The SN74CB3T3125PWR is a 4-bit bus switch with independent output-enable (OE) inputs.  
- It provides low-power, high-speed switching between two ports.  
- Designed for partial-power-down applications with Ioff protection.  

### **Features:**  
- **Low Power Consumption:** ICC < 1μA (max)  
- **Bi-Directional Switching:** Supports both input and output signal routing.  
- **5V Tolerant I/Os:** Allows interfacing with 5V logic levels.  
- **Fast Switching:** Enables high-speed data transfer.  
- **Ioff Protection:** Prevents current backflow when powered off.  
- **ESD Protection:** Exceeds 2000V (HBM) and 1000V (CDM).  

This device is commonly used in signal routing, hot-swapping, and level-shifting applications.
